Urgent question -- I am so sorry to be asking what has probably been asked many times. But in my general incompetence/very beginning of learning how to use this amazing programme, I am not even able to find what topic refers to this question!

I have a DVD with menu and chapters (it is of my work, but someone else made it -- all legal). I have copied the VIDEO_TS folder on my computer and opened it on MyDVDEdit.
